Main results of ESTMAP energy system modelling Energy system models were successfully coupled with ESTMAP database on 1. large-scale storage potential in EU28 to assess its role in the energy system. Model results allowed the selection of specific technologies and locations 2. from the geographic large-scale storage potential database. Some interesting observations can be made on the role of large-scale energy 3. storage based on the example modelling analysis. Capturing time-dynamics effectively is essential for quantifying the demand 4. for flexibility options, such as energy storage. ESTMAP project delivers an excellent toolbox to further quantify the role of 5. large-scale energy storage and to assess key drivers and risks.
Conclusions and recommendations regarding subsurface storage potential assessment • Necessity for large scale energy storage development is expected (in mid- and long-term) • Now is the time to invest in developing the key knowledge: • Long lead times on development • Technological breakthrough needed for certain technologies • Benefit from synergies with other research areas (geothermal, CCS) • Make use of key E&P technical knowledge while they are still active (Joint Industry Projects) • Subsurface is key to developing flexible, large-scale storage solutions for Electricity, Gas and Heat related energy sources
Recommendations regarding subsurface assessment • Harmonize and extend geological mapping and characterization of subsurface reservoirs that are considered suitable for energy storage. Complete parameter definitions; • Establish harmonized methodology to assess energy storage capacities and performance indicators for different subsurface technologies. Include stochastic approaches to assess uncertainties and confidence levels; • Further explore and confirm site-specific potential for multiple storage options and uniformly rank these options on the basis of technical, economic and environmental criteria; • Select and develop sites that are primary targets for potential energy storage demonstration projects; • Set up the appropriate procedures and means to maintain and regularly update the udergorund storage potential database with new contributions from third parties (industry) and national research!
